The first release of the Staticfile buildpack after 2020-08-07 will no longer include NGINX versions 1.17.x. These NGINX versions will no longer be supported upstream. Please migrate your static content apps to supported versions of NGINX before that time.
Note: As 1.17.x is the current default version of NGINX in the buildpack, the default NGINX version will be updated to 1.19.x as a part of this removal. If you’d like to use a different NGINX version, please configure your application to select that version.
As always, the buildpacks team is happy to answer questions you may have about this deprecation in the #buildpacks Slack channel.
